RDFS provides primitives for defining lightweight schemas for RDF triples. It allows defining classes of resources and relations between resources, and organizing their hierarchies. RDFS defines domains and ranges for relations, and provides semantics and inference rules for reasoning about subclasses, subproperties, and types of resources.
RDF is a general method to decompose knowledge into small pieces, with some rules about the semantics or meaning of those pieces. The point is to have a method so simple that it can express any fact, and yet so structured that computer applications can do useful things with knowledge expressed in RDF.
Semantic Web technologies (such as RDF and SPARQL) excel at bringing together diverse data in a world of independent data publishers and consumers. Common ontologies help to arrive at a shared understanding of the intended meaning of data.
However, they don’t address one critically important issue: What does it mean for data to be complete and/or valid? Semantic knowledge graphs without a shared notion of completeness and validity quickly turn into a Big Ball of Data Mud.
The Shapes Constraint Language (SHACL), an upcoming W3C standard, promises to help solve this problem. By keeping semantics separate from validity, SHACL makes it possible to resolve a slew of data quality and data exchange issues.
Presented at the Lotico Berlin Semantic Web Meetup.

Neno/Fhat: Semantic Network Programming Language and Virtual Machine Specific...Marko Rodriguez
• The Semantic Web is a distributed, flexible modeling framework.
• The Semantic Web is primarily descriptive in nature. The Semantic Web is used to describe web-pages, services, systems, etc.
• Neno is an object-oriented language that was designed specifically for the Semantic Web.
• Fhat is a virtual machine represented in the Semantic Web.
• With Neno/Fhat the Semantic Web now has a procedural component. The Semantic Web now includes object methods, algorithms, and computing machines.
• The Semantic Web can be made to behave like a distributed, general-purpose computer. Not just an information repository.
Walking Our Way to the Web - Fabien Gandon
The Web: Scientific Creativity, Technological Innovation and Society
XXVIII Conference on Contemporary Philosophy and Methodology of Science
9 and 10 March 2023
University of A Coruña
The prospect of Walking our Way to the Web may sound strange to contemporary readers of this article for whom the Web is omnipresent. However, the slogan of the World Wide Web Consortium (W3C) has been, for years, and remains today, to lead “the Web to its full potential” meaning we haven’t reached that potential yet, whatever it is. The first architect of the Web himself, Tim Berners-Lee, said in an interview in 2009: “The Web as I envisaged it, we have not seen it yet. The future is still so much bigger than the past”. And he is still very active, together with the W3C members and Web experts world-wide, in proposing evolutions of the Web architecture to improve its growing usages and applications. In this article we will review the path that led us to the actual Web, the shape it is taking now and the possible evolutions, good and bad, we can identify today. This will lead us to consider the distance that we witness between the initial vision and the reality of the Web today, and to reflect on the possible divergence between the potential we see in the Web and the directions it could take. Our goal in this article is to reflect on how we could walk the delicate path to the full potential of the Web, finding the missing links and avoiding the one too many links.
a shift in our research focus: from knowledge acquisition to knowledge augmen...Fabien Gandon
EKAW 2022 keynote by Fabien GANDON: "a shift in our research focus: from knowledge acquisition to knowledge augmentation"
While EKAW started in 1987 as the European Knowledge Acquisition Workshop, in 2000 it transformed into a conference where we advance knowledge engineering and modelling in general. At the time, this transition also echoed shifts of focus such as moving from the paradigm of expert systems to the more encompassing one of knowledge-based systems. Nowadays, with the current strong interest for knowledge graphs, it is important again to reaffirm that our ultimate goal is not the acquisition of bigger siloed knowledge bases but to support knowledge requisition by and for all kinds of intelligence. Knowledge without intelligence is a highly perishable resource. Intelligence without knowledge is doomed to stagnation. We will defend that intelligence and knowledge, and their evolutions, have to be considered jointly and that the Web is providing a social hypermedia to link them in all their forms. Using examples from several projects, we will suggest that, just like intelligence augmentation and amplification insist on putting humans at the center of the design of artificial intelligence methods, we should think in terms of knowledge augmentation and amplification and we should design a knowledge web to be an enabler of the futures we want.

A Never-Ending Project for Humanity Called "the Web"
Fabien Gandon, Wendy Hall
https://hal.inria.fr/WIMMICS/hal-03633526
In this paper we summarized the main historical steps in making the Web, its foundational principles and its evolution. First we mention some of the influences and streams of thought that interacted to bring the Web about. Then we recall that its birthplace, the CERN, had a need for a global hypertext system and at the same time was the perfect microcosm to provide a cradle for the Web. We stress how this invention required to strike a balance between the integration of and the departure from the existing and emerging paradigms of the day. We then review the pillars of the Web architecture and the features that made the Web so viral compared to competitors. Finally we survey the multiple mutations the Web underwent no sooner it was born, evolving in multiple directions. We conclude on the fact the Web is now an architecture, an artefact, a science object and a research and development object, and of which we haven't seen the full potential yet.
CovidOnTheWeb : covid19 linked data published on the WebFabien Gandon
The Covid-on-the-Web project aims to allow biomedical researchers to access, query and make sense of COVID-19 related literature. To do so, it adapts, combines and extends tools to process, analyze and enrich the "COVID-19 Open Research Dataset" (CORD-19) that gathers 50,000+ full-text scientific articles related to the coronaviruses. We report on the RDF dataset and software resources produced in this project by leveraging skills in knowledge representation, text, data and argument mining, as well as data visualization and exploration. The dataset comprises two main knowledge graphs describing (1) named entities mentioned in the CORD-19 corpus and linked to DBpedia, Wikidata and other BioPortal vocabularies, and (2) arguments extracted using ACTA, a tool automating the extraction and visualization of argumentative graphs, meant to help clinicians analyze clinical trials and make decisions. On top of this dataset, we provide several visualization and exploration tools based on the Corese Semantic Web platform, MGExplorer visualization library, as well as the Jupyter Notebook technology. All along this initiative, we have been engaged in discussions with healthcare and medical research institutes to align our approach with the actual needs of the biomedical community, and we have paid particular attention to comply with the open and reproducible science goals, and the FAIR principles.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
